There's a good reason why Jules and Jim resonates with Emily so strongly. She is in love with her neighbour, Gabriel, the boyfriend of one of her only French friends Camille. Not only does this cause her psychological strife, it ruins her friendship with Camille and complicates her feelings for Gabriel. Emily's reaction to Jules and Jim is perfectly reasonable, though. A good love triangle film should make viewers reconsider their own thoughts on sex, relationships and love.
